GIZ Indonesia was named as finalist of the The smarter E AWARD 2025 in the Category "Oustanding Projects" for the application Dynamic Solar-Powered Off-grid Cooling for Island Fishery Communities.
In the Solar Ice Maker project, up to 1.2 metric tons of block ice are produced off-grid using solar energy on a daily basis. The idea behind it is to provide smaller fishing communities with access to improved cold chains, with the aim of helping them gain better market access and, in turn, generate a higher income. A further benefit is that more continuous cooling also goes a long way toward helping avoid food losses. The system requires around 100 kWh to produce one metric ton of ice. A heat storage tank (brine) combined with a 24 kWh battery storage system ensures continuous ice production. The control system automatically adjusts ice production according to solar irradiation levels, the state of charge of the battery and the brine temperature by varying the compressor frequency.
